United Visual Products' Wet/Dry Erase Board with Sliding Doors provides a larger, more unobstructed display area than a traditional enclosed board with swinging doors. This stylish board features an elegant satin anodized aluminum frame and a ratchet lock that secures doors to prevent tampering. Choose from white dry erase or black dry erase - both are available in porcelain (magnetic) or melamine (non-magnetic). Magnetic porcelain on steel boards can easily be turned into directories. White porcelain on steel boards work with both dry erase and wet erase markers or can be used with magnetic strips. Black porcelain on steel boards work with wet erase markers, chalk markers or magnetic strips. United Visual Products' 60" wide by 36" high Wet/Dry Erase Board with Sliding Doors and Aluminum Frame is backed by a one-year warranty.
